2015 Lincoln EcoBoost vs the Ike Gauntlet
The EcoBoost performance was pretty impressive and I couldn't help notice how relatively low the RPM's were too. Link

I was surprised to see that the Ecoboost horsepower rating (380 HP) was listed in the 2015 brochure as requiring 93 octane premium fuel. I did not realize that was a requirement. Either way, impressive numbers.
That is why we bought a 2015 Expedition with the 3.5 Ecoboost rather than a 2015 Navigator. The Navigator requires premium, the Expedition only requires regular. Just annoyed to me to have to pay a 30 cent per gallon premium just to own our previous Navigator. Did not want to do it again.
You got suckered. Its the same engine. WHy would the surrounding vehicle determine octane requirements? It doesn't...
This sounds very similar to early 200x Acura MDX vehicles which Acura called out premium octane fuel for. A few years later Honda come out with the Pilot. Exact same motor/drivetrain only requiring 87 octane. Acura owners were like WTH, but eventually smelled through the BS and now most in the know just run 87 octane and let the knock sensors and adjustable timing do their thing.
